SPECIFICATION forming part of Letters Patent Naazsoe, dated April Y15, Iseo.

Application led February 10, 1890'. SerialNo. 339,802. (No model.) f

To all whom it may concern: l

Be it known that I, WILLIAMv DUECHTIING, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Refrigerator-Cars; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a partof this specification.

This invention relates to refrigerating apparatus applied to railway-cars, and has for one of its objects to provide a construction by which bodies of ice may be formed in the car instead of being placed therein after their formation elsewhere.

The invention also has for one of its objects to provide an arrangement of a series of pans one above another within a partial inclosure, whereby air may circulate downwardlyT over and under the several pans in a zigzag course, and thus become more effectively cooled.

Another object of the invention is to provide a construction whereby an upper pan when filled to the proper depth will overflow into a subjacent pan, and thus the entire series of pans may be filled by delivering water into the upper one.

The invention has for still another of its objects to provide a construction whereby cold air may be driven forcibly in ahorizontal direction as it leaves the cooling-chamber.

In the accompanying drawings, which illustrate one form in which my invention may be constructed, Figure l is a central vertical longitudinal section-of a car provided with my improved apparatus. Fig. 2 is a horizontal section in the line 2 2 of Fig. 1. Fig. 3 is a vertical transverse section .in the indirect line 3 3 of Fig. 2.

A represents a car, of which a is the floor, a the roof, and a2 the end.

B is an inclosure, here shown as extending across one end of the car and open at both the top and bottom to permit a downward movement of air through the same.

C C are a series of horizontal pans supported one over another by ribs c c or otherwise within the inclosure B. Each pan C is provided with one or more holes in its bottom, each surrounded by a vertical tube o',

extending tol such height within the pan as it may be desired to fill the same with water preparatory to freezing the latter. The tubes c of one pan are arranged out ofl line with the corresponding tubes of the subjacent pan, so that when water is poured into the uppermost of vsaid pans it willlill the latter to the height of the tubes c 'thereof and then overiio'w through said tubes into the subjacent pan, so that in this manner all the pans may be filled from above to a required depth. The lowermost pan is provided with an overiiowpipe c2, which leads outside the car, as indicated in Fig. 3, said pipe being provided eX- ternally to the car with a cock o3, by which, when the pans shall have been lled, said overflow-,pipe may be closed.

C represents a spout leading through the side of the car above the uppermost pan C and adapted to connect outside the car with a hose, by which water may be sent t0 the pans C C from any suitable source of supply.

D is a brine-chamber adjacent to the panchamber or inclosure B. In the present drawings said brine-chamber D is shown located adjacent to the wall of the car and between it and the pan-chamber B; but obviously it may,

if desired, be extended around the pan-cham.-4

l. It is intended that the pipe E of one car may be temporarily coupled with the corresponding pipe of the adjacent car and connected with a stationary ammonia-pump located adjacent to the track on which the cars stand, and by the circulation of -ammonia in a state of expansion after compression through the pipe and coil E in the usual manner the temperature of the brine within the chamber D will be lowered to such an extent as to congeal the Water in the pans C, thus forming a series of thin blocks of ice in said pans.

For the circulation of the air within the car in Contact with the ice in the pans C C, any suitable form of openings out of line with each other through or at the ends or sides of said pans may be provided.

In the present-- case the openings through the tubes c are berv is illustrated by arrows.

brine in the chamber D has been reduced to utilized for that purpose, and the zigzag course of thedescending air through the pan-cham- After the the proper temperature the valves E in the pipe E' are closed and the pipes of one car des srably uncoupled from those of another. The congelation of the water in thepans will be rapid and the blocks of ice completelyfo rmedlA f before the `ear will be put in motion.

F is a hood applied to the open bottom of the inclosure or pan-chamber B, the front vertical portion of said hood having an opening f, preferably in the middle thereof,` through V whichV a relatively narrow stream of air will pass Afrom the pan-chamber with greater `ra-` pidity,` and therefore to a greater distance than if the opening were of the full Width of the car. Several openings f may be provided in the hood, if desired, theirsize being deter-V minedwith reference to the force or velocity desired to be given to the air-streams; f

I claim aS :my invention:- L 1. The eombination,with a,car,.of a brine` chamber containing a coil for the passage of ammonia, an inelosure adjacent to the brineehamblerpand open at top and bottom for the admission anddischargeof air, andaseries of pans arranged within said inclosure, one v above another, and 'with a space between them, passages being provided by which air may descendfrom the top to the bottom ofA `the inclosure and `horizontally between the pans, substantially as described.

2. The `combination of the brine-chamber D, containing'a coil E, the contiguous panchamber B, open at top and bottom, and a series of pans C, provided with tubes c',- ar" ranged out of line iwith eachother, substan tially asdeseribed, and'for the purposes set forth.

3. In combinationwith thepamehamberJA B, a hood F, covering the open bottom of the pan-chamber and provided Jwith acontracted opening fzinits `front portion. n

In ltestimony that Iclaim the foregoing `as.`

my invention Lafx my signature inwpresence of two witnesses. WILLIAM DUECHTING.
